| 240 mL | 8.12 oz | 8.45 oz |
Why 240 mL Matters in Daily Life
When you hear 240mL, it may not sound like a big deal. But this seemingly simple measurement plays a surprisingly vital role in our daily routines, especially in cooking, nutrition, medicine, and even product packaging. Understanding how much 240mL really is and how often we encounter it can improve your health decisions, save time in the kitchen, and reduce waste.
This article dives deep into what 240mL really means, where it shows up in everyday life, and why knowing it matters more than you might think.
What is 240 mL?
240 milliliters (mL) is a metric measurement of volume commonly used around the world. In the United States, it’s roughly equivalent to 1 U.S. cup.
| Metric Volume | U.S. Customary Equivalent |
|---|---|
| 240 mL | 1 U.S. cup |
| 120 mL | ½ cup |
| 60 mL | ¼ cup |
This makes 240mL a go-to standard in recipes, nutrition labels, and product packaging.
Why 240 mL Is a Standard Measurement
The U.S. Food and Drug Administration (FDA) defines one serving size of many beverages as 8 fluid ounces, which equals 240mL. This standard helps regulate nutrition labeling, allowing for consistent calorie and nutrient comparisons across products.
It’s also a widely accepted portion size in:
- Cooking and baking recipes
- Nutrition facts panels
- Beverage servings
- Pharmaceutical dosing
According to the FDA’s Reference Amounts Customarily Consumed (RACC), many drinks and some yogurts are standardized at 240mL per serving.
240 mL in Nutrition and Diet
One of the most important contexts where 240mL matters is diet and health. Whether you’re reading a label or measuring a serving, this volume is everywhere.
Nutrition Labels Use 240 mL
Most nutrition facts labels for beverages and liquid foods (like milk, juice, and soup) are based on a 240mL serving. That means when a label says “120 calories per serving,” it often refers to 240mL not the whole bottle.
“Understanding that 240 mL equals one serving can help prevent accidental overeating.” Dr. Susan Mitchell, Registered Dietitian
Daily Fluid Intake Guidelines
Health authorities recommend daily water intake in liters, but people often measure fluids in cups. Since 240mL = 1 cup, you can quickly estimate your fluid intake:
| Gender | Recommended Intake (cups) | Volume (liters) |
|---|---|---|
| Men | 13 cups | 3.0 L |
| Women | 9 cups | 2.2 L |
Knowing how much 240mL is helps convert your hydration goals into understandable portions.
Cooking with 240 mL: Accuracy Matters
In the kitchen, 240mL is the cornerstone of many recipes particularly in baking, where precision is critical.
Common Ingredients Measured in 240 mL:
- Milk Most baking recipes call for 1 cup of milk.
- Water Used in soups, stews, or boiling grains like rice or quinoa.
- Broth Often used in recipes in 1-cup increments for flavor.
- Oil Particularly in baking or salad dressing recipes.
Why Precision in Volume Matters
A little extra or too little liquid can ruin a recipe. For instance, 240mL of milk in a pancake recipe affects both texture and consistency. When recipes use the cup as a measure, they’re referring to 240mL, so it’s key to use a proper measuring cup for liquids, not just eyeball it.
Medicine and 240 mL: Dosing Accuracy
In healthcare and medicine, accurate dosing is crucial and 240mL is a key volume in prescriptions and over-the-counter instructions.
Examples of 240 mL in Medical Contexts:
- Liquid medications may be prescribed in doses such as “Take 30 mL with 240mL of water.”
- Bowel preparation kits before colonoscopies often instruct patients to drink 240mL every 15 minutes.
- Hydration instructions for patients recovering from illness often include drinking 240mL every 1–2 hours.
Mistaking this amount can lead to underdosing or overdosing, both of which may have serious health consequences.
240 mL in Baby Feeding and Formul
In infant nutrition, 240mL plays a significant role in bottle feeding and formula preparation.
Baby Formula Guidelines:
- A full 8-ounce bottle equals 240mL.
- Many baby bottles are marked with both ounces and mL, usually up to 240mL for one full feeding.
Parents preparing formula often follow this volume for a single feeding session. A typical guideline is:
“Newborns eat around 60–90 mL per feeding, but by 4–6 months, a baby may consume close to 240 mL at a time.”
Household Products Sold in 240 mL Size
Many everyday household products come in 240mL containers, including:
- Shampoo and conditioner bottles
- Body lotion tubes
- Mouthwash bottles
- Kitchen condiments (like salad dressings or soy sauce)
Why manufacturers use 240mL:
- Easy to price
- Compact for shipping
- Standard volume for “trial” or “regular” sizes
This consistency also helps consumers compare value across brands. A bottle labeled 240mL allows you to calculate cost per mL easily when comparing with a larger or smaller container.
Converting 240mL to Other Units
Here’s a quick conversion table for 240mL into other common units of volume:
| Unit | Equivalent to 240 mL |
|---|---|
| U.S. Cups | 1 cup |
| U.S. Fluid Ounces | 8 fl oz |
| Tablespoons (U.S.) | 16 tbsp |
| Teaspoons (U.S.) | 48 tsp |
| Liters | 0.24 L |
| Pints (U.S.) | 0.5 pint |
This is especially helpful when reading international recipes or shopping online for imported goods.
Case Study: 240 mL in Meal Planning
Scenario: A family of four wants to serve soup for dinner using a homemade recipe. The recipe serves two and requires 240mL of broth per person.
Calculation:
- For 4 people, total broth needed = 240mL × 4 = 960 mL
- They buy a 1-liter (1000 mL) carton of broth. Perfect amount with a little to spare.
By understanding what 240mL looks like, they avoid overbuying and reduce food waste.
Visualizing 240 mL in Real Life
To put things into perspective, here are some relatable visuals for 240mL:
- A standard coffee mug typically holds about 240 250 mL.
- A juice box often contains 200–250 mL.
- A single-serve soda can (U.S.) is about 355 mL just a bit more than 1 cup.
So when someone says “drink a cup of water,” they usually mean 240mL.
Conversion Formula: How to Convert 240 mL to Ounces
Here’s the conversion formula to calculate fluid ounces from milliliters:
Fluid Ounces (oz) = Milliliters (mL) divided by 29.5735
Other Conversion Examples
| Volume (mL) | US oz (rounded) | UK oz (rounded) |
|---|---|---|
| 100 mL | 3.38 oz | 3.52 oz |
| 200 mL | 6.76 oz | 7.04 oz |
| 240 mL | 8.12 oz | 8.45 oz |
| 500 mL | 16.91 oz | 17.60 oz |
| 1000 mL | 33.81 oz | 35.20 oz |
US vs UK Ounces: Why the Confusion?
The term “ounce” varies based on region. US and UK fluid ounces are not the same:
| Type of Ounce | Volume (mL) |
|---|---|
| US fluid ounce | 29.5735 mL |
| UK fluid ounce | 28.4131 mL |
So, if you’re converting 240 mL to ounces UK, the result is:
240divided by 28.4131 equals approximately 8.45 oz (UK)
Always check your recipe’s origin because that one ounce difference can throw things off.
Visual Reference: mL to Ounce Conversion Chart
| Milliliters | US oz | UK oz | Cups (US) | Tablespoons (US) | Teaspoons (US) |
|---|---|---|---|---|---|
| 100 mL | 3.38 | 3.52 | 0.42 | 6.76 | 20.29 |
| 200 mL | 6.76 | 7.04 | 0.85 | 13.52 | 40.58 |
| 240 mL | 8.12 | 8.45 | 1.00 | 16.23 | 48.70 |
| 500 mL | 16.91 | 17.60 | 2.08 | 33.82 | 101.44 |
| 1000 mL | 33.81 | 35.20 | 4.17 | 67.63 | 202.88 |
Case Study: 240 mL in Baby Bottles
When it comes to infant nutrition, precision isn’t just helpful it’s essential. One of the most common volume references in baby care is 240mL, especially for bottle feeding. Whether you’re a new parent navigating feeding schedules or a caregiver preparing formula, understanding what 240mL means can make feeding more efficient and safe.
How Much Is 240 mL in a Baby Bottle?
240mL equals 8 fluid ounces, which is the standard full bottle size for many baby bottles in the U.S. and internationally. Most bottle brands, including Philips Avent, Dr. Brown’s, Tommee Tippee, and Comotomo, mark their largest bottles up to 240mL, recognizing it as a typical full feeding volume for older infants.
| Age of Baby | Typical Bottle Volume (mL) | Notes |
|---|---|---|
| 0–1 month | 60–90 mL | Small, frequent feedings |
| 1–3 months | 90–120 mL | Feeding volume gradually increases |
| 3–6 months | 120–180 mL | Fewer but larger feedings |
| 6+ months | 180–240 mL | Typical full bottle size |
Formula Feeding: Why 240 mL Matters
Baby formula is usually mixed in scoops per 60 mL of water. So when preparing 240 mL of formula:
- You’ll need 4 scoops of powdered formula.
- Add to 240mL of water, not the other way around adding water after powder can lead to over-concentration.
According to the American Academy of Pediatrics, over-diluting or over-concentrating formula can be harmful to an infant’s kidneys and nutrient absorption.
“Always use the correct ratio of formula to water. 240 mL equals 8 ounces, which often aligns with 4 level scoops of most powdered formulas.” AAP Infant Nutrition Guide
Breast Milk and 240 mL Bottles
For breastfeeding moms who pump and store milk, 240 mL bottles are ideal for storing larger quantities as babies grow. In early months, most babies may drink 60–120 mL per feeding, but by 6 months, a baby can consume close to 240 mL in one session.
Storage tips:
- Label bottles with volume and date.
- Use 240mL breast milk storage bottles or bags to portion feedings accurately.
- Never microwave milk in bottles warm gently in water.
Real-Life Scenario: Feeding Twins
Case Study Example:
Jennifer, a new mom of twin boys, feeds them simultaneously every 3 hours. By month 4, each baby consumes approximately 240mL per feeding.
Feeding calculation per day:
- 240 mL × 2 babies × 6 feedings = 2,880 mL of formula per day
- That equals 12 cups (since 240mL = 1 cup)
By standardizing her feedings with 240 mL bottles, Jennifer:
- Reduces guesswork and ensures consistent nutrition.
- Minimizes the risk of under- or over-feeding.
- Plans formula purchases more accurately, saving money and time.
Choosing the Right Bottle Size
Choosing bottles that hold up to 240mL means:
- Fewer refills per feeding.
- Easier transition as the baby grows.
- Better portion control.
Most major bottle brands offer 240mL options, labeled as 8 oz or “Stage 2” bottles. Many also include dual measurement marks (mL and fl oz), making feeding easy regardless of unit preference.
240 mL in Cooking and Recipes
In baking, precision is crucial. For instance, 240mL of milk is 8.12 oz, not just 8 oz. Volume varies by density, so 240 mL might weigh differently depending on the type of dry ingredient.
Use a scale to convert 240mL to grams for dry ingredients.
How 240 mL Compares to Other Common Measurements
| Comparison | Value |
|---|---|
| 240 mL in US oz | 8.12 oz |
| 240 mL in UK oz | 8.45 oz |
| 240 mL in cups | 1 cup (US) |
| 240 mL in tbsp | 16.23 tbsp (US) |
| 240 mL in tsp | 48.70 tsp (US) |
| 240 mL in liters | 0.24 L |
| 240 mL in pints | about 0.51 US pints |
How to Measure 240 mL Accurately
Getting the measurement of 240 mL right can make or break a recipe, affect your baby’s nutrition, or even impact how well medication works. While 240 mL might equal a standard U.S. cup, not all measuring tools are created equal and not all methods are accurate.
Here’s how to measure 240 mL accurately in various situations using the right tools.
Tools for Measuring 240 mL
| Tool | Best For | Notes |
|---|---|---|
| Liquid measuring cup | Cooking, baking, formula | Must have a spout and mL markings |
| Graduated baby bottles | Infant feeding, formula prep | Often marked up to 240 mL (8 oz) |
| Measuring syringe | Medicine, baby care | High precision, ideal for smaller amounts |
| Kitchen scale (metric) | When converting mL to grams | Useful for measuring by weight if density is known |
| Digital measuring cup | Precision cooking, baking | Combines volume and weight with digital readout |
| Measuring spoons | In absence of a measuring cup | 16 tablespoons = 240 mL |
Tips for Measuring 240 mL Correctly
1. Use a clear, graduated liquid measuring cup
These are designed for volume and typically show both metric (mL) and U.S. customary (cups/oz) units. Pour the liquid slowly and get eye level with the line not above or below to avoid parallax error.
2. Don’t use dry measuring cups for liquids
Dry cups are made for ingredients like flour or sugar. Using them for liquids often results in spillage and under-measuring. Always use a liquid measuring cup with a spout.
3. For baby formula, use bottle markings
Most baby bottles are clearly marked up to 240 mL. Fill water first to the correct line, then add the appropriate number of scoops. Do not measure formula volume by eye alone.
4. Use tablespoons in a pinch
If you don’t have a liquid measuring cup, you can measure 16 U.S. tablespoons, as each tablespoon equals 15 mL:
- 240 ÷ 15 = 16 tablespoons
But this should be your backup method it’s easy to spill or miscount.
5. Use a kitchen scale for accuracy
If the substance you’re measuring has the same density as water (which is true for many liquids), then 240 grams = 240 mL. This is especially helpful in professional baking.
Visual Estimations (When You Have No Tools)
While it’s always best to use proper tools, sometimes you’re stuck. Here’s how to estimate 240 mL in a pinch:
- Standard coffee mug Most mugs hold about 240–250 mL
- Juice box Typically contains 200–250 mL
- One large ladle Roughly 120 mL, so use two full ladles
These aren’t perfect, but they help you get close when measuring tools aren’t available.
Why Measurement Accuracy Matters
In Recipes:
Too little liquid makes baked goods dry and crumbly. Too much can ruin the texture.
In Infant Nutrition:
Overfeeding or underfeeding can cause digestive issues or malnutrition in babies.
In Medication:
Incorrect doses even by 10 mL can cause side effects or reduce effectiveness.
“Just 10 mL off in medication can have consequences, especially for children or the elderly.” Dr. Lisa Huang, Pediatric Pharmacist

FAQs: 240 mL to oz Conversion
What is 240 mL in ounces?
240milliliters is equal to 8.12 U.S. fluid ounces (oz).
This is based on the U.S. fluid ounce, where 1 fl oz = 29.5735 mL.
Calculation: 240÷ 29.5735 ≈ 8.12 fl oz
Is 240 mL the same as 8 ounces?
In U.S. fluid measurements, yes 240mL is commonly rounded to 8 oz for simplicity, especially in nutrition labels and recipes.
However, technically, 8 fl oz equals 236.59 mL, so 240 mL is just slightly more.
How many fluid ounces in 240 mL (UK vs US)?
| Region | Fluid Ounces in 240 mL |
|---|---|
| U.S. | 8.12 fl oz |
| UK | 8.45 fl oz (Imperial) |
The UK Imperial fluid ounce is 28.41 mL, which is slightly less than the U.S. version. That’s why UK fluid ounces appear higher for the same mL amountWhy do recipes round 240 mL to 8 oz?
Standardization. In U.S. recipes and food labels, 1 cup = 8 oz = 240 mL is a commonly accepted approximation, even though 8 oz is technically 236.59 mL. The round number simplifies cooking, packaging, and feeding measurements.
Is 240 mL a full cup?
Yes. In most U.S. recipes and measurements, 1 cup = 240 mL. This standard is used across cooking, baby bottle sizes, and dietary recommendations.
How can I measure 240 mL if my cup only shows ounces?
Look for the 8 oz line on your liquid measuring cup. Since 240 mL = 8.12 oz, the 8 oz mark is a close approximation. For greater accuracy, use a digital scale or measuring cup with milliliter markings.
Why does the exact conversion matter?
In most casual uses (like drinking water or making soup), the 0.12 oz difference won’t matter.
But in precision baking, infant feeding, or medication, those few milliliters can affect the outcome. Always go with more accurate tools when precision is critical.
Can I convert 240 mL to dry ounces?
No milliliters measure volume, and dry ounces measure weight (mass).
To convert to dry ounces, you need the density of the substance. For example, 240 mL of water is about 8.47 dry ounces, but 240 mL of flour is much less by weight.
Quick Reference: 240 mL in Other Units
| Unit | Equivalent |
|---|---|
| U.S. Fluid Ounces | 8.12 fl oz |
| Imperial Fluid Ounces | 8.45 fl oz |
| Cups | 1 cup |
| Tablespoons | 16 tbsp |
| Teaspoons | 48 tsp |
| Liters | 0.24 L |
Final Thoughts
Converting 240 ml to oz may seem simple, but when precision matters in health, recipes, or measurements small differences add up. Always know whether you’re using US or UK ounces. Use accurate tools for measurement. Understand the context: cooking, medical, or casual use.
When in doubt, stick with metric. But when ounces are the norm, use 8.12 US fluid ounces for 240 mL.
